Evidence of Absence

This is a recorded presentation describing a statistical software package called "Evidence of Absence" that can be used to provide evidence of compliance with incidental take permits. It will be useful to wildlife managers and wind energy operators to estimate, with reasonable certainty, that a certain number of birds or bats have been killed at wind energy facilities,

Sagebrush, grasses, and forbs in a shrub-steppe ecosystem

Determining aboveground biomass of sagebrush, grasses, and forbs is important for estimating fuel loads, measuring carbon storage, and assessing habitat quality in shrublands. Remote sensing may offer a more efficient alternative to common, labor intensive methods of measuring aboveground biomass that are difficult to apply across large areas. Researchers from the USGS are

Environmental DNA Samples

Samples from various aquatic species and other material necessary to create environemntal DNA (eDNA) assays are stored at the Snake River Field Station in Boise. Water samples from aquatic ecosystems are compared against the assays to identify the presence and location of species in those ecosystems.
